Low Intracranial Pressure Treatment Strategies for Chronic Subdural Hematoma Patients

Not Applicable

• Conditions: Chronic Subdural Hematoma
• Interventions: Drug: Atorvastatin plus Dexamethasone; Behavioral: low intracranial pressure strategy treatment

• Registration Number: NCT04607447
• Lead Sponsor: Huashan Hospital

Brief Summary

The proportion of the elderly population is increasing rapidly. Chronic subdural hematoma has become the most common cause of surgery in neurosurgery for elderly patients. The standard treatment for cSDH is mostly surgery. Clinically, we often encounter elderly patients with certain underlying diseases or organ dysfunction, especially preexisting cardiovascular disease or medication history like anticoagulant or antiplatelet drugs, resulting in poor surgical tolerance, high risk during anesthesia and hematoma recurrence. At present, the mechanism of cSDH is not completely clear. Our previous observational studies had shown significant correlation between cSDH and intracranial hypotension. So we would like to conduct a randomized, controlled, multi-center clinical study to explore the effectiveness and safety of low intracranial pressure treatment strategies for patients with chronic subdural hematoma.

Recruitment & Eligibility

• Status: UNKNOWN
• Sex: All
• Target Recruitment: 160

Inclusion Criteria

• patients above 14 yrs with chronic subdural hematoma confirmed by cranial imaging;
• patients with MGS-GCS score ≤1 point, showing no signs of neurological deficits caused by CSDH or characteristics of high intracranial pressure;
• patients with MGS-GCS score ≥1 point, but with medication history of anticoagulant or antiplatelet drugs, coagulation dysfunction so that they are unsuitable or intolerant of surgery although they are in stable condition;

Exclusion Criteria

• women pregnant or in lactation
• those who are allergic to atorvastatin, hypoxamethasone;
• patients with brain herniation or altered mental status;
• patients with primary diseases like tumors, hemorrhagic diseases or some other critically serious conditions( eg.multiple organ failure);
• patients with uncontrollable diabetes and heart failure
• patients with preexisting chronic abdominal diseases (such as inflammatory bowel disease) or lung tumors or digestive system neoplasm
• Patients with abnormal liver function
• patients had taken atorvastatin or dexamethasone, ACEI in the past one week
• other conditions not eligible to enroll the trial confirmed by two individual doctor

Primary Outcome Measures

Name	Time	Method
Modified Rankin Scale	three months	difference of Modified Rankin Scale between two groups; The modified Rankin Scale is a commonly used scale for measuring the degree of disability or dependence in the daily activities of people who have suffered a neurological disability. The scale runs from 0-6, running from perfect health without symptoms to death.
Extended Glasgow Outcome score	three months	difference of Extended Glasgow Outcome score between two groups; This score is used to measure the outcome after neurological disease. It defines 5 categories of possible outcomes after a brain injury, which is from good recovery(5) to death(1).
subdural hematoma volume	three months	difference of hematoma volume in subdura between two groups
Markwalder scale	three months	difference of Markwalder scale between two groups;The Markwalder Scale is designed to measure the chronic subdural hematoma scale. This scale is categorized into four grade. Grade 0 denots the patient neurologically normal, whereas grade 4, the highest grade, denotes the worst neuological assessment.
